Dolphin Video

In the United States, facilities are regularly inspected by federal agencies to ensure that a high standard of welfare is maintained.

Organizations such as World Animal Protection and the Whale and Dolphin Conservation campaign against the practice of keeping them in captivity.

Captives have vastly reduced life expectancies, on average only living into their 20s, although there are examples of killer whales living longer, including several over 30 years old, and two captive orcas, Corky II and Lolita, are in their mids.

In the wild, females who survive infancy live 46 years on average, and up to 70—80 years in rare cases. Wild males who survive infancy live 31 years on average, and up to 50—60 years.

Critics claim captive life is stressful due to these factors and the requirement to perform circus tricks that are not part of wild killer whale behavior.

Although dolphins generally interact well with humans, some attacks have occurred, most of them resulting in small injuries.

The record-holder of documented orca fatal attacks is a male named Tilikum , who has lived at SeaWorld since There are documented incidents in the wild, too, but none of them fatal.

While dolphin attacks occur far less frequently than attacks by other sea animals, such as sharks , some scientists are worried about the careless programs of human-dolphin interaction.

Read, a biologist at the Duke University Marine Laboratory who studies dolphin attacks, points out that dolphins are large and wild predators, so people should be more careful when they interact with them.

Several scientists who have researched dolphin behaviour have proposed that dolphins' unusually high intelligence in comparison to other animals means that dolphins should be seen as non-human persons who should have their own specific rights and that it is morally unacceptable to keep them captive for entertainment purposes or to kill them either intentionally for consumption or unintentionally as by-catch.

A military dolphin is a dolphin trained for military uses. A number of militaries have employed dolphins for various purposes from finding mines to rescuing lost or trapped humans.

The military use of dolphins , however, drew scrutiny during the Vietnam War when rumors circulated that the United States Navy was training dolphins to kill Vietnamese divers.

Dolphins are still being trained by the United States Navy for other tasks as part of the U. Navy Marine Mammal Program. The Russian military is believed to have closed its marine mammal program in the early s.

In the press reported that dolphins trained to kill by the Soviet Navy had been sold to Iran. Dolphins are an increasingly popular choice of animal-assisted therapy for psychological problems and developmental disabilities.

For example, a study found dolphins an effective treatment for mild to moderate depression. For example, it is not known whether dolphins are more effective than common pets.

In some parts of the world, such as Taiji, Japan and the Faroe Islands , dolphins are traditionally considered as food, and are killed in harpoon or drive hunts.

Dolphin meat is dense and such a dark shade of red as to appear black. Fat is located in a layer of blubber between the meat and the skin.

When dolphin meat is eaten in Japan, it is often cut into thin strips and eaten raw as sashimi , garnished with onion and either horseradish or grated garlic , much as with sashimi of whale or horse meat basashi.

When cooked, dolphin meat is cut into bite-size cubes and then batter-fried or simmered in a miso sauce with vegetables.

Cooked dolphin meat has a flavor very similar to beef liver. There have been human health concerns associated with the consumption of dolphin meat in Japan after tests showed that dolphin meat contained high levels of mercury.

The Japanese government recommends that children and pregnant women avoid eating dolphin meat on a regular basis.

Similar concerns exist with the consumption of dolphin meat in the Faroe Islands , where prenatal exposure to methylmercury and PCBs primarily from the consumption of pilot whale meat has resulted in neuropsychological deficits amongst children.

However, the Faroe Islands populations also eat significant numbers of fish. The study of about Faroese children showed that prenatal exposure to methylmercury resulted in neuropsychological deficits at 7 years of age.

Tropical bottlenose whale I. Dolphins can tolerate and recover from extreme injuries such as shark bites although the exact methods used to achieve this are not known.

The healing process is rapid and even very deep wounds do not cause dolphins to hemorrhage to death. Furthermore, even gaping wounds restore in such a way that the animal's body shape is restored, and infection of such large wounds seems rare.

The study, published in the journal Marine Mammal Science, suggests that at least some dolphins are up to the shark challenge with research finding that many dolphins survive attacks using everything from sophisticated combat moves to teaming up against the shark.

Some dolphin species are at risk of extinction, especially some river dolphin species such as the Amazon river dolphin, and the Ganges and Yangtze river dolphin , which are critically or seriously endangered.

A survey found no individuals of the Yangtze river dolphin , which now appears to be functionally extinct. Pesticides , heavy metals, plastics, and other industrial and agricultural pollutants that do not disintegrate rapidly in the environment concentrate in predators such as dolphins.

Various fishing methods, most notably purse seine fishing for tuna and the use of drift and gill nets , unintentionally kill many dolphins.

Dolphin safe labels attempt to reassure consumers that fish and other marine products have been caught in a dolphin-friendly way. The dolphins are netted only while fishermen are in pursuit of smaller tuna.

Albacore are not netted this way, making albacore the only truly dolphin-safe tuna. Dolphins and other smaller cetaceans are also hunted in an activity known as dolphin drive hunting.

This is accomplished by driving a pod together with boats and usually into a bay or onto a beach. Their escape is prevented by closing off the route to the ocean with other boats or nets.

Dolphins are hunted this way in several places around the world, including the Solomon Islands , the Faroe Islands , Peru , and Japan , the most well-known practitioner of this method.

By numbers, dolphins are mostly hunted for their meat , though some end up in dolphinariums. Despite the controversial nature of the hunt resulting in international criticism, and the possible health risk that the often polluted meat causes, thousands of dolphins are caught in drive hunts each year.

Dolphins have long played a role in human culture. Dolphins are sometimes used as symbols, for instance in heraldry. In Greek myths , dolphins were seen invariably as helpers of humankind.

Dolphins also seem to have been important to the Minoans , judging by artistic evidence from the ruined palace at Knossos. During the excavations of a major Mycenaean city at Iklaina , a striking fragment of a wall-paintings came to light, depicting a ship with three human figures and dolphins.

Dolphins are common in Greek mythology , and many coins from ancient Greece have been found which feature a man, a boy or a deity riding on the back of a dolphin.

A dolphin rescued the poet Arion from drowning and carried him safe to land, at Cape Matapan , a promontory forming the southernmost point of the Peloponnesus.

There was a temple to Poseidon and a statue of Arion riding the dolphin. He drowned but was transfigured as the marine deity Palaemon, while his mother became Leucothea.

At Corinth, he was so closely connected with the cult of Poseidon that the Isthmian Games , originally instituted in Poseidon's honor, came to be looked upon as the funeral games of Melicertes.

Phalanthus was another legendary character brought safely to shore in Italy on the back of a dolphin, according to Pausanias.

Dionysus was once captured by Etruscan pirates who mistook him for a wealthy prince they could ransom. After the ship set sail Dionysus invoked his divine powers, causing vines to overgrow the ship where the mast and sails had been.

He turned the oars into serpents, so terrifying the sailors that they jumped overboard, but Dionysus took pity on them and transformed them into dolphins so that they would spend their lives providing help for those in need.

Dolphins were also the messengers of Poseidon and sometimes did errands for him as well. Dolphins were sacred to both Aphrodite and Apollo.

When heraldry developed in the Middle Ages , not much was known about the biology of the dolphin and it was often depicted as a sort of fish.

Traditionally, the stylised dolphins in heraldry still may take after this notion, sometimes showing the dolphin skin covered with fish scales. Dolphins are present in the coat of arms of Anguilla and the coat of arms of Romania , [] and the coat of arms of Barbados has a dolphin supporter.

The dolphin is said to be among the creatures which heralded the goddess' descent from the heavens and her mount, the Makara , is sometimes depicted as a dolphin.

The Boto , a species of river dolphin that resides in the Amazon River , are believed to be shapeshifters, or encantados , who are capable of having children with human women.

There are comparatively few surviving myths of dolphins in Polynesian cultures, in spite of their maritime traditions and relevance of other marine animals such as sharks and seabirds ; unlike these, they are more often perceived as food than as totemic symbols.

Dolphins are most clearly represented in Rapa Nui Rongorongo , and in the traditions of the Caroline Islands they are depicted similarly to the Boto, being sexually active shapeshifters.

The renewed popularity of dolphins in the s resulted in the appearance of many dolphinaria around the world, making dolphins accessible to the public.

Criticism and animal welfare laws forced many to close, although hundreds still exist around the world.

In the United States , the best known are the SeaWorld marine mammal parks. Various species of dolphins are kept in captivity.

These small cetaceans are more often than not kept in theme parks, such as SeaWorld , commonly known as a dolphinarium. Bottlenose dolphins are the most common species of dolphin kept in dolphinariums as they are relatively easy to train, have a long lifespan in captivity and have a friendly appearance.

Hundreds if not thousands of bottlenose dolphins live in captivity across the world, though exact numbers are hard to determine. Other species kept in captivity are spotted dolphins , false killer whales and common dolphins , Commerson's dolphins , as well as rough-toothed dolphins , but all in much lower numbers than the bottlenose dolphin.

There are also fewer than ten pilot whales , Amazon river dolphins , Risso's dolphins , spinner dolphins , or tucuxi in captivity.

The number of killer whales kept in captivity is very small, especially when compared to the number of bottlenose dolphins, with 60 captive killer whales being held in aquaria as of [update].

From to , 55 whales were taken from the wild in Iceland, 19 from Japan, and three from Argentina.

These figures exclude animals that died during capture. Organizations such as the Mote Marine Laboratory rescue and rehabilitate sick, wounded, stranded or orphaned dolphins while others, such as the Whale and Dolphin Conservation and Hong Kong Dolphin Conservation Society , work on dolphin conservation and welfare.

India has declared the dolphin as its national aquatic animal in an attempt to protect the endangered Ganges River Dolphin.

The Vikramshila Gangetic Dolphin Sanctuary has been created in the Ganges river for the protection of the animals. There is debate over the welfare of cetaceans in captivity, and often welfare can vary greatly dependent on the levels of care being provided at a particular facility.

In the United States, facilities are regularly inspected by federal agencies to ensure that a high standard of welfare is maintained. Organizations such as World Animal Protection and the Whale and Dolphin Conservation campaign against the practice of keeping them in captivity.

Captives have vastly reduced life expectancies, on average only living into their 20s, although there are examples of killer whales living longer, including several over 30 years old, and two captive orcas, Corky II and Lolita, are in their mids.
